Almost all houses can benefit from a loft conversion

Updated: Mar 10, 2020

Depending on the roof structure and planning constraints, a loft conversion is one of the most straightforward ways of gaining extra space.

Loft Conversions are an ideal way to get extra value from your home without extending the footprint of your premises. Most houses are suitable for some kind of loft conversion, subject to assessment.

How to calculate your loft's head height?

Is my house suitable for a loft conversion?

There are a number of factors that decide whether your loft is suitable for conversion: Head Height Take a measurement from the top of the ceiling joist (1) to the bottom of the ridge timber (2). This measurement should be an absolute minimum of 2.2m.

  • Pitch Angle The higher the pitch angle (3) of the roof, the more useable floor area your loft conversion can have. 40° or more is considered suitable for a conversion.

  • Obstacles Fixed obstacles such as chimneys, ventilation pipes, and water tanks need to be taken into account before deciding on any loft conversion plans.

  • End Shape The shapes of the ends of the loft – Gable (straight) or Hipped (angled) – will affect complexity and floor space calculations.

  • Age of Structure Pre 1960s lofts generally have a more conversion-friendly structure than houses built post-1960s.
